Scientists accidentally create mutant enzyme that eats plastic bottles
The breakthrough, spurred by the discovery of plastic-eating bugs at a Japanese dump, could help solve the global plastic pollution crisis

Scientists have created a mutant enzyme that breaks down plastic drinks bottles – by accident. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles.

The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug.

The international team then tweaked the enzyme to see how it had evolved, but tests showed they had inadvertently made the molecule even better at breaking down the PET (polyethylene terephthalate) plastic used for soft drink bottles. “What actually turned out was we improved the enzyme, which was a bit of a shock,” said Prof John McGeehan, at the University of Portsmouth, UK, who led the research. “It’s great and a real finding.”

Image of the Week - September 10, 2018

CIL:39062 - http://cellimagelibrary.org/images/39062

Description: This light micrograph shows the outside edge of two seminiferous tubules of a mouse testis. This section is a 1um thick transverse section, stained with toluidine blue to highlight the cells, with the nucleus staining a darker blue. The dark blue line separating the two seminiferous tubules consists mostly of myoid (muscle) tissue. The majority of cells seen in this image (arranged in layers) are germ cells, which, by repeated cell division, eventually produce spermatozoa. Chromosomes are visible in most of the nuclei of the cells. The cell with a deeply-stained nucleus and even darker nucleolus is a Sertoli cell (‘nurse cell’) that has fine cytoplasmic extensions branching between the other cells to nurture the developing germ cells.
